纠错（四种方式改写）.
1.Tom said I'm wantching TV.
2.Tom asked me' Do you g o to the libary?
3.Tom asked me when I had.
3错了、
3.Tom asked me ' When did you buy the book?
答
1 Tom said he was watching TV
2 Tom asked me if I went to the libary
3 Tom asked me when I bought the book
1 Tom在说自己,所以这里用第三人称 He
2 3 这里分别在问"我",所以问句中的you在从句中换成了第一人称"I"
